In summary, Ubuntu Server edition focuses on stability, performance, efficiency and flexibility suitable for hosting enterprise grade production workloads. It is specially optimized for usage within data centers, servers and virtualized infrastructure.

Key Differences Between Ubuntu Desktop and Server

While Ubuntu Desktop and Server share the same fundamental codebase, they diverge in several areas to cater to their respective user segments:

1. User Interface

The most prominent difference is that Ubuntu Desktop provides a full graphical desktop environment while Ubuntu Server relies solely on a text based command-line interface.

Ubuntu Desktop uses the user-friendly GNOME desktop environment. It is specially tailored for mouse/keyboard input and visual feedback allowing regular end-users to easily interact with the system.

In contrast, Ubuntu Server has no graphical shell. Administration and operations occur entirely through a CLI (command line interface) accessed via SSH or direct terminal login. This reduces resource overhead and attack surface making it ideal for servers.

2. Installation Process

The Ubuntu Desktop edition uses a simple GUI based installer activated from a Live mode desktop environment while Ubuntu Server uses a more complex text based installer.

On Ubuntu Desktop, installation is designed to be very simple and intuitive similar to installing a typical OS or software application. Users boot into a Live environment desktop allowing exploration before committing to install. The graphical installer then guides through the process requiring minimal intervention.

Ubuntu Server instead boots directly into a text based installer driven by system configuration options. There is no Live mode preview. The install process is optimized to allow extensive customization of server parameters like disk partitioning, network settings etc. Additional packages can also be bundled based on the planned server role.

3. Applications and Services

Ubuntu Desktop comes preloaded with a standard suite of end-user applications like office tools, media apps and web browser while Ubuntu Server ships with server oriented components like web server, database etc.

A fresh Ubuntu Desktop install comes with hundreds of common applications like LibreOffice, Firefox, Evolution Mail, Shotwell Photo Manager etc. that appeal to regular desktop users. The default set strives to meet most day-to-day computing needs.

On the other hand, Ubuntu Server comes with only the bare essential underlying system packages. But it allows selection of common server add-on bundles during installation like DNS, print server, database server, web server (LAMP), mail server, FTP among other roles. This allows rapid creation of appliances fine-tuned for specific usage scenarios.

4. Hardware Support

Ubuntu Desktop supports a wider range of consumer grade hardware like wireless cards, sound cards, graphic cards typically found in client machines while Ubuntu Server focuses on enterprise server class components.

Ubuntu Desktop ships with default drivers and firmware covering most consumer laptops and desktops including newer models. It supports modern graphics standards like OpenGL enabling desktop visual effects and gaming capabilities. Sound is enabled by default with multiple audio device choices.

Ubuntu Server limits components to standardized server grade hardware parts recommended for enterprise reliability and performance. This allows optimization but reduces flexibility in terms of supported device diversity. Non-essential components like sound cards are not enabled by default.

5. Updates and Support

While both Ubuntu Desktop and Server receive security updates, Desktop updates are more frequent while Server updates focus on stability and longer timeframe support.

Ubuntu Desktop follows a fixed 6 month update cycle delivering new features and innovation at a rapid pace suitable for end-users. Support lasts for 9 months. Long Term Support (LTS) versions are provided every two years with extended 5 years support.

In contrast, Ubuntu Server release cycle is driven more by long term stability demands. Production rollout schedules are decoupled from update releases focusing only on incremental security and maintenance patches. LTS versions provide 5 years support with possibility to extend up to 10 years for an additional fee making it ideal for long life enterprise server deployments.

6. Resource Requirements

Ubuntu Desktop requires more base system resources in terms of CPU, RAM and disk space compared to Ubuntu Server to support the graphical environment and apps.

A typical Ubuntu Desktop install requires at least 2GB RAM and a multi-core CPU. 20GB free disk space is recommended for reasonable performance. High end visual effects or gaming may demand additional resources.

Ubuntu Server on the other hand has a much smaller footprint consuming minimum resources even on lower end hardware. It can work with just 512MB RAM, 10GB storage and even a single core CPU. This allows cost-effective deployment of multiple Ubuntu Server instances as virtual machines.

7. Customization

Ubuntu Desktop provides easier GUI based customization for end-users while Ubuntu Server relies primarily on low level command line tweaks and tunes.

On Ubuntu Desktop, users can easily tweak visual themes, dock position or launchers using GUI config tools. Additional user apps and language packs can be installed using the Ubuntu Software Center frontal. Experimental or unstable features can be activated using GUI toggles.

For Ubuntu Server, configurations require directly editing text config files and system scripts. Additional software typically gets added from CLI either manually or via custom provisioning tools. Performance tuning relies on sysctl kernel tweaks, boot parameters and daemons behavior overrides to optimize for traffic, security or hardware specifics.

8. Pricing and Support

Both editions of Ubuntu are freely available however commercial enterprise grade support plans differ amongst the Desktop and Server variant.

Desktop Ubuntu does not have a paid enterprise support offering currently. Users can access the community forums and wikis for unofficial troubleshooting assistance and tips. Third party support vendors also offer Desktop Linux support plans.

Ubuntu Server on the other hand offers comprehensive enterprise grade paid support plans via Canonical allowing 24×7 coverage with stringent SLA guarantees ideal for critical production server workloads. Support extends to underlying infrastructure like virtualization and cloud platforms too.

The wide spectrum of available support services includes phone/email technical support, managed OS updates, security compliance, dedicated CVE patch coverage, legal assurance, and technology roadmap guidance. Custom engineering support like optimization, porting assistance etc. are also available.
